Title: Frequency synthesizer
Inventor: MURAI TETSUSHI
IPC: H03L7/18
Filed: 1988-07-14
Abstract: PURPOSE:To obtain an open loop gain characteristic stable over a broad band by controlling the open loop gain of a loop filter of a frequency synthesizer by an open loop gain control signal in response to a frequency division control signal. CONSTITUTION:A phase locked loop controls a divided frequency N by using a frequency division control signal 8 from a frequency control circuit 7 and acts like a frequency synthesizer. In this case, switches S1A-S1D switching resistors R1A-R1D in an active filter 6a by using an open loop gain control signal 9 of the active loop filter from an external frequency control circuit 7 are controlled according to a frequency division control signal. That is, when a parallel combined resistance R1(N) of the resistors R1A-R1D switched on according to the frequency division number N of a frequency divider 3 is set in multi-stage according to the frequency division number N, even if the frequency division number N is fluctuated into 2XN, 3XN-, the fluctuation of the open loop gain KS of the synthesizer is suppressed by controlling the resistance R1(N) to be 1/2,1/3-.

Patent JP-H098400-A (JP)
Title: Semiconductor laser having separated current path and grating and fabrication thereof
Inventor: MIYAZAWA SEIICHI
IPC: H01S5/00
Filed: 1995-06-19
Abstract: PURPOSE: To increase the fabrication yield by a structure wherein the layer structure in the direction vertical to a grating surface has conductivity type of at least PNP and NPN and constriction of current is separated from confinement of light. CONSTITUTION: When Si doped GaAs is grown on  111} A face, p-type GaAs is grown whereas n-type GaAs is grown when Si doped GaAs is grown on  100} face. This feature is utilized for separating a current supply part from grating. Consequently, a current flows as shown by 19 on a slope corresponding to 15 and arrives effectively at an active layer 5. On the contrary, PNP structure is formed at a flat part corresponding to  100} and no current flow. In other words, carriers do not flow easily into the region 12 where a grating is formed and the light is collected in the center 20 of the ridge. Since the carriers are nor captured at the interface of grating but consumed effectively, a DFB laser having low threshold current can be realized.

Patent JP-S5798015-A (JP)
Title: Constant voltage power supply device
Inventor: HOSAKA MASAO
IPC: G05F1/10
Filed: 1980-12-12
Abstract: PURPOSE:To stabilize an AC load to be constant voltage in a simple circuit by carrying out AC phase control after A/D conversion is applied to the level of an approximate value of a load, the result of which is fetched to a microprocessor as a digital input where processing by operations are performed. CONSTITUTION:The applied voltage to a load 3 is detected by a transformer 14, converted into an effective value by an approximate effective value conversion circuit 40, converted into digital value by an A/D converter 41 and fed back to a microprocessor (MPU). Here a sampling cycle on applying A/D conversion by the converter 41 becomes a delay in the feed back which generates an error: therefore, the zero cross of the AC voltage of the power supply is detected by a zero cross generator 42 and, at the moment of generation of a zero cross pulse, the internal counter of the MPU is started to decide the phase angle of ignition for phase control. Thereby the load voltage can be controlled at constant for the control of switch-on position of a high speed switching element 2.

Inventor: TAKEMURA MASAMI
IPC: E04B2/96
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To provide a hanging-bolt attaching structure which reduces cost and enhances workability by using universal parts. SOLUTION: The connecting rod 19 of a hanging bolt 25 is passed through the through holes 18C, 18D of a transom 12 at the projected corner part of a curtain wall 10, and the transom 12 is clamped by a hexagonal nut 21 and a high nut 24 fitted around the connecting rod 19 and located respectively at the top and the bottom. Therefore, since the normal nuts 21, 24 readily available as universal parts are used in attaching the connecting rod 19 to the transom 12, special parts are not necessary as in conventional cases, so that cost reduction can be achieved. Since the work of tightening the nuts 21, 24 and the like is performed easily with universal tools, workability can also be enhanced.

Title: Master controller for railway vehicle
Inventor: TAKAHASHI TORU
IPC: B60L15/00
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To reduce a master controller in size by providing a first sensor for sensing the rotary angle of a steering wheel in a first range, and a second sensor for sensing a rotary angle of the wheel only when the wheel is disposed at a prescribed position narrower than the first range, and discriminating the presence of faults in the operation of each sensor. SOLUTION: With respect to a true angle of a steering angle is θ, an angle detected by a rotary angle sensor 5 is set of θR. This θR is input to a notch deciding unit 8, which decides and outputs the notch of 'B4',..., 'B1', 'N', and 'P1',..., 'P4' within the range of a (specified angle ±5 deg.). A controller and a prime mover during organizing are operated based on the notch output. Meanwhile, a proximity sensor 7 is set so as on to be turned on when 3 deg.<=θ<=3 deg. for 'N'. Only when it is turned on, is the output θR of the sensor 5 also input to a fault deciding unit 9. The unit 9 decides whether θR is such that '-5 deg.<=θR<=5 deg.'. If θR falls within this range, the unit 9 decides as being a normal sensor but if it does not, the unit 9 decides as being abnormal sensor.

Furthermore, a chilled water manipulated value MV2' from the data conversion portion 23 is inputted to a chilled water valve correction arithmetic portion 26 where a flow amount of fluid to the heat exchanger which is measured by the flow meter 3 is multiplied to the manipulated value MV2' to generate a manipulated value MV2. A chilled water valve is controlled in response to this manipulated value MV2. Accordingly, a rapid temperature change during a temperature control can be restricted.
